If f(x) = 3x and g(x) = 1/3x which expression could be used to verify that g(x) is the inverse of f(x)? a. 3x(x/3) b. (1/3x)(3x) c.1/3(3x) d. 1/3(1/3x)

Step-by-step explanation:

To verify if two functions are inverse, we have to find the composition of such functions, that is:

; which results must be the variable to be inverse functions.

We know that: .

Replacing on the composition:

Therefore, the expression that has to be used to verify that these functions are inverse is C.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
